A biographer wrote Kronrod gave ideas "away left and right, quite honestly being convinced that the authorship belongs to the one who implements them."

[3] Growing up, he studied math with D. O. Shklyarsky in school and in 1938 entered the Department of Mechanics and Mathematics at Moscow State University.

During World War II he was rejected for military service because at the time students of higher classes were given deferments.

During next four years he continued his studies at the University, simultaneously working, from 1945, in the computational branch of the nuclear energy research and development Kurchatov Institute.

In his last undergraduate year, Kronrod studied with Nikolai Luzin the teacher of many of the Soviet Union's finest scientists.

The preparation required for this reduced the numbers of participants, but those who remained, including Robert Minlos and Anatoli Vitushkin, derived great benefit.

[3] Kronrod's position was formally at the Institute of Physics, which meant that his students had to register with other advisers, accounting for the decline of the circle into a series of friendly meetings.

[3] At the Moscow Institute for Theoretical and Experimental Physics (ITEF or ITEP) during 1950–1955 Kronod collaborated with physicists, among them Isaak Pomeranchuk and Lev Landau.

For providing theoretical physics with numerical solutions he received the Stalin Prize and an Order of the Red Banner of Labour.

He employed women in ITEP's coding and card punching groups, believing that female computing staff members are more accurate than males.

He served with Leonid Kantorovich and others on a cabinet ministry commission and oversaw the computation of the country's material expenditures to correct price formation.

His last position was heading a Central Geophysical Expedition laboratory that processed drilling data where he made calculations for gas and oil exploration, but he was not challenged by this work.

[3] He slowly recovered when a stroke took his speech and ability to read and write but was forced to resign at the Central Geophysical Expedition and stop all work on math.
